Over the span of a 35-year career as a professional photographer, Joe McNally knows what it means to chase light. Known for his work with studio and off-camera lighting, McNally is just as well-versed in the art of natural light as he is artificial. In his PIX 2015 talk, he discusses the choices he makes about lighting to help bring out the most from his location and subject. And one thing you can be sure about with Joe: he's got a lot to say on the subject.
